Dominic Létourneau alerted us to the first software release from the ManyEars project. What does the software do? "The ManyEars project makes use of an array of microphones to perform sound source localization, tracking, and separation. It is designed to provide auditory capabilities to mobile robots, but it can equally be used for video conferencing or other applications. It is based on the FlowDesigner development environment." Microphones can make inexpensive sensors for mobile robots. If your robot doesn't sense sound yet, this might be an interesting way to add that capability. ManyEars is Free Software licensed with the GNU GPL.
